CMake Error at PCL can not be found on this machine

As an AI language model, I do not have access to your machine to provide a specific solution to your problem. However, here are some general troubleshooting steps that you can follow:

1. Make sure that PCL is installed on your machine. You can check this by running the following command in your terminal:

pcl-config --version

If PCL is not installed, you can download it from the PCL website.

2. Check if PCL is included in your CMakeLists.txt file. You should have the following lines in your file:

find_package(PCL 1.7 REQUIRED)
include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})

3. Make sure that the PCL library path is added to your LD_LIBRARY_PATH environment variable. You can do this by adding the following line to your .bashrc file:

export LD_LIBRARY_PATH=/path/to/pcl/lib:$LD_LIBRARY_PATH

Replace /path/to/pcl/lib with the actual path to the PCL library on your machine.

4. If you have installed PCL in a non-standard location, you can specify the path to the PCL library in your CMakeLists.txt file by adding the following line:

set(PCL_DIR /path/to/pcl)

Replace /path/to/pcl with the actual path to the PCL library on your machine.

5. If none of the above steps work, try reinstalling PCL and make sure that all dependencies are installed.
